Low power and low cost projection system

Abstract

A system comprising of low cost and low power projection engine comprising of means of producing non-coherent light source, means of condensing non-coherent light into narrow beams, means of focusing and scanning narrow beam light on screen where as image is projected on screen by producing light for each pixel of image. Source of non-coherent light can be LED.

What is claimed is: 
     
         1 . A system comprising of projection engine which further comprising of
 means of producing non-coherent light for each pixel   means of focusing and scanning light on screen   where as image is projected on screen by producing light for each pixel of image in sequence, by focusing light for each pixel on screen and by scanning produced light across the screen so that all pixels are illuminated on screen in time multiplexed fashion to form image.   
     
     
         2 . The said means of producing non-coherent light as set forth in  claim 1  comprises of color light source. 
     
     
         3 . The said means of producing non-coherent light as set forth in  claim 2  comprises of color LED light source. 
     
     
         4 . The said means of producing non-coherent light as set forth in  claim 3  comprises of at least RED, GREEN or BLUE color LED light source. 
     
     
         5 . A system comprising of projection engine which further comprising of
 means of producing non-coherent light   means of condensing non-coherent light into narrow beams   means of focusing and scanning narrow beam light on screen   where as image is projected on screen by producing light for each pixel of image in sequence, by condensing said light into narrow beam, by focusing light for each pixel on screen and by scanning said narrow light beam across the screen so that all pixels are illuminated on screen in time multiplexed fashion to form image.   
     
     
         6 . The said means of producing non-coherent light as set forth in  claim 5  comprises of color light source. 
     
     
         7 . The said means of producing non-coherent light as set forth in  claim 6  comprises of color LED light source. 
     
     
         8 . The said means of producing non-coherent light as set forth in  claim 7  comprises of at least RED, GREEN or BLUE color LED light source. 
     
     
         9 . A system comprising of projection engine which further comprising of
 means of producing non-coherent light of plurality of color beams   means of combining plurality of color beams into fewer beams   means of focusing and scanning combined light beams on screen   where as color image is projected on screen by producing light beams of plurality of colors for each pixel of image in sequence, by combining said plurality of color beams into fewer beams, by focusing said combined light beams for each pixel on screen and by scanning said combined light beams across the screen so that all pixels are illuminated on screen in time multiplexed fashion to form image.   
     
     
         10 . The said means of producing non-coherent light as set forth in  claim 9  comprises of color LED light source. 
     
     
         11 . The said means of producing non-coherent light, as set forth in  claim 10  comprises of at least RED, GREEN or BLUE color LED light source. 
     
     
         12 . The said means of combining plurality of color beams as set forth in  claim 9  produces a single combined beam of light.
